OIL-GAGE "FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed August 29. 1919. Serial No. 320 641,

To all whom it may concern:

Be it known that I, Gnome ll. WALLACE, a citizen of the "United States, and a resident of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Oil-Gage for Automobiles, of which the following is a full, clear, and exact description.

This invention relates to improvements in oil gages for automobiles, an object of the invention being to provide a simple, praotical and inexpensive attachment which may be convenientl placed in position on a well known type 0 car in general use and which will indicate the level of oil in the crank case of the engine, whenever the device is examined.

A further object is to provide an attachment which can be connected to the car by simply providing a hole in the splash or metal plate, between the car body and the step of the car, and connecting the device in an existing screw-threaded opening in the crank case, preferably the one which is ordinarily used to receive a lower petcock.

ith these and other objects in View, the invention consists in certain novel features 'of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a view partly in end elei'ation and partly in section illustrating my improved device on the car.

Fig. 2 is a view in longitudinal section through the device.

Fig.'3 is a view in elbow.

Fig. 4 is an enlarged View in elevation of the indicator blade.

1 represents a car section through the of the well known Ford type in general use, having the step or run ning-board 2, body 3, and an intervening plate 4, which is known in the trade as a splash and will be hereinafter referred to as such.

5 represents the crank case, which contains oil in its lower portion to lubricate the engine. Ordinarily it is difficult to tell just how much lubricant there is in the crank case.

An elbow 6 having a smaller externally screw threaded end 7 is screwed into a threaded opening in the rear end of the crank case 5, toward the bollom and the larger internally Sl'lf'Wllll'lilllWl end of the elbow receives a threaded collar 15 scour-- ing the end of a straight tubular easing ii to the elbow. The said canine extends at an inclination laterally and upwardly, so that its outer end may project through an opening 9 in the splash 4, where it is held or may be secured in any desired manner; The straight thbular casing-including therein the'tube Q and the larger end of the elbow (1. with which it is in line and which forms its lower portion.;is oi' such length that its end will reach the splash with'the easing at the desired inclination.

An indicating blade 10 is located in the casing 8 with its inner end in the elbow (l. and a knob 11 on the outer end of the blade fits snugly and forms a closure for the outer end of the casing. By removing the closure the user also removes the indicator blade.

The oil 12 in the crank case maintains the same level in casing 8 in the crank case and when the blade .10 is withdrawn itwill shou the level of oil.

The blade 10 is provided with a roughened surface 13 at one edge to .cause the oil to adhere thereto, and is divided by lines 14 into spaces containing captions follows: llry Danger OK, and Excess.

The operator thus knows the condition of lhe nil in the crank case whenever he exam- III! :ihe blade, and this examination can be "ul ill made by reason of the convenient lo- 'ali'dl of the device, said location being a factor in the exceedingly simple and inexpensive construction which has been pro- (loved, as well. causing the blade to be taken out where it can be seen mo st readily and where any drip from the blade is unob jeclionable. n fact it is unnecessary to reimn'i' the blade entirely, as the user can look down on its markings while its end remains in the tube, and the term removable" here in is used in a general sense.

The distance between marks, or the lengths of zones marked on this blade or rod. are substantially greater than the disstances between the corresponding; oil levels in the crankcase, the relation being determined in accordance with the intended inclination of the tubular casing 8. In applying the device in the preferred manner to a car, the hole 9 is therefore cut in the splash at a definite height, or at a definite distance from the step or body. The spread in; of tho marks upon tluhladv is an advantagv in that it l'ai'ililatvs roading. lm iol tant advantagvs and (-haravtvriutiru ol' the inn'nlion arilhu umplivity and wonht'illlt'lll l'lwnlnn'hs of tho (lllltt. its cash of alriilirnlion.
